SunControl - DIY Solar Power for Arduino and Raspberry Pi Projects

Ever wanted to build your own Solar Powered Raspberry Pi or Arduino project? You CAN build your own solar powered projects. We have combined three popular boards for solar systems into one inexpensive package.  

We combined the USB PowerControl, SunAirPlus and the SwitchDoc Labs Watchdog Timer into one board.   We removed a couple of features that most users weren't using (and can be done by inexpensive other boards), specifically the space for the servo chip and the second A/D converter.    We found that most customers were using timing to do sun tracking rather than optical tracking.   Makes sense!

SunControl is customizable with your software and hardware. Note that the battery and solar panel plugs on SunControl are of type JST-PH 2 pin.

SunControl Allows you to:

 

  • Use Solar Power to Charge and Run Your small Computers
  • Measure and Monitor the Performance of your system.
  • Understand what is happening in real time with your Solar Panels, batteries and computers!
  • Turn your Raspberry Pi / Arduino on and off to avoid brownouts and SD Card damage
  • Use the onboard Hardware WatchDog timer to dramatically improve your reliability of the your project

 

Now Available - Protect your LiPo battery from cold and hot charging by adding a NTC Thermistor to SunControl

NTC Thermistor 10K ohm 1% B3950 L75mm Wired + 10K Ohm Metal Film Resistor (0450-NTCTHERM-DSBT)

Features

- Combines Three Boards (SunAirPlus, USB PowerControl and WatchDog Timer)

- Easy to Use! No Soldering

- Solar Power Your System

- Charge your Batteries

- Control Your Computer Power

- Gather Important Data

- Improve Your Reliability

- Qi Wireless Charging Too!

The major features of the SunControl board are:

  • Uses 6V Solar Cells
  • Use 3.7V LiPo Cells for batteries
  • Built-In USB Port Power Control using Computer GPIO Control or Battery Sensing
  • Has LiPo to 5V voltage boost built in
  • Directly powers Raspberry Pi / Arduino
  • Works Raspberry Pi (3.3V) GPIO and Arduino (5.0V) GPIO
  • Built-in data gathering chips for system currents /voltages
  • Charges iPhones and other phones or devices
  • Approximates an MPPT (Maximum Power Point Tracking) charging system
  • Comes with Grove connectors

A Few Technical Specifications

  • 1500 mA from Solar Panels (Max, self regulating)
  • 1000mA max instantaneous charge to LiPo Battery
  • 1000mA supply to 5V USB Connector
  • USB Hysterisis: Battery 3.7V turn on, 3.3 turn off (this prevents what is called called hammering - power turns on, computer uses power, battery voltage drops and power turns off. Battery recovers, turns on power, computer uses power, battery voltage goes down, shutting off power - rinse and repeat)
  • 3 Channel INA3221 based I2C Current Measurement - 12 bit, 3000 samples/second 0.8 mA resolution

Even Qi Wireless Charging Works with SunControl

We hooked up a Qi Wireless charger to SunControl and got great results right off the bat. Think of the applications for robots!

Application Notes

  • Using the SunControl WatchDog Timer (coming soon)
  • Using SunControl in a Raspberry Pi Solar Powered System (coming soon)
  • Using SunControl in an Arduino Solar Powered System (coming soon)
  • Using SunControl in an ESP8266 Solar Powered System (coming soon)
